SPA B l I PLUG AND COIL CONNECTED.

Application fled :Iay 8,

To all whom it may concern:

Be it known that I, PAUL KonLorr, a citizen of the United States, residing at Mamaroneck, in the county of Westchester and State of New York, have invented new and useful Improvements in Spark Plug and Coil Connectors, of which the following is a specification.

The invention relates necting spark plugs and coil box of an automobile and t e principal object is to provide a' device of this nature which shall be simple of construction, consisting of a single part, cheap to manufacture, and highly to means for conetlicient for the purpose for which it is designed. 7.

Another object isto provide a device of this nature which shall possess a certain sp'ringiness tending constantly to force both ends into engagement with the binding post.

Another object is to this nature which may readily modified to place and secure the other without entirely removing the nuts from the binding post.

Another object is to produce a device of this nature having a plurality of apertures each of which is adapted for co-action with a binding post so that a degree of adjustment is provided which is at present not possible.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawing, in which Figure 1 is a perspective view showing a coil box and spark plugs connected by the present invention.

Figure 2 is a detail View of one of the connecters,-per se.

Figure 3 is a sectional view of the end of one of the connecters constructed to embody also the property of a spark intensifer.

Like characters of reference refer to like parts in all views.

Referring to the drawing in detail, 10 represents the coil box of any automobile, and is provided with a plurality of binding posts 11 having caps or nuts 12. A corresponding plurality of spark plugs are indirovide a device of f 1922. Serial No. 559,111

cated at 13 each provided with a binding post 14 and terminal nut 15.

Under present practice insulated wires connect the binding posts 11 with the respective binding post 14, said wires including the members or terminal elements which are soldered to the principal portion of the wire. This form of construction is quite costly, and it not infrequently happens that the insulation burns from these wires causing considerable annoyance and sometimes great damage. 7

The present invention comprises a metal strip 16 which may be of any suitable and desired width and which ispreferably made of some spring metal. The strip is provided with a plurality of apertures 17, the end ones of which communicate with jaws or free openings 18 having teeth 20. If desired the strip may be covered with an insulation coat, although this is not deemed necessary in most cases. As shown in Figure 3 the connecters have been coated with solder as shown at 19, the coating being greatly exaggerated in the drawing so as to illustrate the point. The application of solder as shown gives a greater resistance, and consequently effects the same result as if a spark intensifer were utilized.

In use any one of the apertures 17 may be connected with a respective binding post 11 and another of the apertures made to receive a respective one of the binding posts 14.- However, when it is desired to put in the connector quickly, the nuts 12 and 15 may be loosened and permits a tight connedtion between the device and the terminal nuts and the o posite jaws pressed home. The nuts are tlien screwed back to place. It will be seen that with this construction, the springiness of the member 16 tends constantly to force the jaws into engagement with the respective binding post.

While I have described what I deem to bethe most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my lnvention, and I therefore do not limit myself to the exact details of forth nor to anything less than the whole of my invention limited only by the append ed claim. a

What is claimed as new 15 construction herein set A device for connecting a terminal of a coil box with the respective terminals of a spark plugv comprising a single piece of relatively springy metal strip having a plurality of apertures arranged near both ends thereof, jaws at the extreme ends of said metal strip and communicating with certain of said apertures, said metal strip means adapted to be bowed in its connection with the respective terminals for constantly 1 forcing the ends of the strip into engagement with the terminals.

In testimony whereof I have affixed my signature.

PAUL KOHLOFF.
